The correct answer is

This condition is called atherosclerosis. Fat and cholesterol build up in the arteries. This buildup is called plaque. The plaque makes the inside of the arteries narrower and stiffer, and less blood can get to the heart. The condition develops slowly and may start in childhood, according to the National Heart, Lung, and Blood Institute (NHLBI). It can affect the arteries of the brain, heart, kidneys, and the arms and legs.

A. StrokeB. ArthritisC. Thickening of the inside of the arteriesD. None of the above

The correct answer is

As you get older, your risk increases. In men, the risk increases after age 45. In women, it increases after age 55. Your risk increases if your father or brother was diagnosed with heart disease before age 55. Your risk also increases if your mother or sister was diagnosed before age 65. These are risk factors you can control: your blood pressure, cholesterol, and weight. You can cut your risk by not smoking and by getting regular exercise.

Both numbers in a blood pressure reading are important. If one or both are high, you have high blood pressure. "Prehypertension" is blood pressure between 120 and 139 for the top number, or between 80 and 89 for the bottom number. A blood pressure in this range makes it more likely that you will develop high blood pressure unless you take steps to prevent it. Doctors divide high blood pressure into two levels, stage 1 and stage 2. Stage 1 high blood pressure is a top number of 140 to 159 or a bottom number of 90 to 99. Stage 2 is a top number of 160 or higher or a bottom number of 100 or higher. Your heart must work harder than normal when your blood pressure is high. If this occurs for an extended time, the heart can enlarge and arteries can become scarred and hardened.

A. 90/70B. 100/80C. 140/90D. 160/100E. C and D

You didn't answer this question.

You answered

The correct answer is

For healthy adults ages 18 to 65, one option the American Heart Association (AHA) recommends is to do an average of 40 minutes of moderate- to high-intensity aerobic exercise 3 to 4 days a week to keep their heart healthy. Brisk walking, swimming leisurely, basketball (shooting around), and ballroom dancing are good choices. Be sure to talk with your doctor before beginning a new exercise program.

A. 10 to 15 minutes on averageB. 20 minutes on averageC. 90 minutes on averageD. 40 minutes on average

A BMI of 25 or higher means that you are overweight. A BMI of 30 or higher means that you are obese. Losing weight may help you prevent heart disease, stroke, and diabetes. Besides helping your heart, maintaining a healthy weight has many other benefits.

A. It can increase blood pressureB. It can increase triglycerides and lower HDL cholesterol levelsC. It can increase the risk for diabetesD. All of the above

8. Drinking a moderate amount of alcohol is considered safe for your heart. What can happen if you drink more?

You didn't answer this question.

You answered

The correct answer is

Too much alcohol can damage the liver and heart, lead to high blood pressure, raise triglycerides, and increase weight, the NHLBI says. Moderate drinking is no more than 2 drinks a day for a man and no more than 1 drink a day for a woman. One drink is 12 ounces of beer, 4 ounces of wine, or 1-1/2 ounces of 80-proof spirits. According to the AHA, some studies have shown a small increase in HDL cholesterol with moderate use of alcohol. This extra HDL cholesterol can remove some of the LDL cholesterol. It can also decrease hardening of the arteries. If you don’t drink alcohol, don’t start drinking to get the benefits of alcohol. You can get same the benefits through exercise and a healthy diet.

Call 911 immediately if you or someone you're with has these symptoms. According to the AHA, chest pain or discomfort is the most common symptom of a heart attack for both men and women. Nausea and vomiting, back or jaw pain, and especially shortness of breath may be more likely in women than men.

A. Crushing pain in the chest accompanied by sweatingB. Pain that spreads from the chest to the shoulders, neck, jaw or armsC. Indigestion or heartburn, nausea and vomitingD. Difficulty breathingE. All of the above
